These three constants govern how the ball behaves at the cushion:
-
μs = 0.212 table friction
(point C in diagram); controls how much the table surface grips the
ball during the bounce higher values slow the ball's slide across
the cloth and transfer more energy into spin.
-
μw = 0.165 cushion friction
(point I in diagram); determines how strongly the cushion face grips
the ball on contact increase it and the ball bites into the cushion,
altering the rebound angle and adding side-spin; reduce it and the
ball skids off more cleanly.
-
ee = 0.98 cushion restitution;
sets how elastic the cushion bounce is values close to 1 return
nearly all the normal velocity, while lower values produce a softer,
more deadened rebound.
Adjust the parameters and share results to discuss. If you have
suggestions for improvement please open an issue on my
GitHub repo.
